Sea World has announced two more acts for its Bands, Brew & BBQ festival this weekend, adding to the list of performers who are defying an unofficial boycott of the park over allegations made by a documentary.

Saturday, Sister Hazel, best known for its 1997 hit “All For You,” will appear. Sunday, blue-collar comedian Larry the Cable Guy will perform.

SeaWorld hasn’t had much time to replace the lineup for the seven-weekend concert and food festival since performers, including Trace Adkins, Martina McBride, Trisha Yearwood, Heart, 38 Special and Barenaked Ladies, canceled their appearances at the park over the documentary “Blackfish.”

Busch Gardens, which is operated by the same parent company as SeaWorld, later saw Pat Benatar and the Beach Boys cancel their performances at the Tampa theme park’s one-weekend version of Bands Brew & BBQ.
